| Abstract |
Xylanosomes, also known as hemicellulosomes, are hemicellulose-degrading nano-scale multienzyme complexes produced by some Firmicutes, Actinobacteria, and Fungi. Here we report the isolation of the MECs produced by Actinotalea fermentas JCM9966, as well as the functional studies and subunit structure revealed by proteomic identifications. The isolated MECs here shows similar particle size with the xylanosomes produced by C. cellulans F16, have several conserved multi-domain proteins, while differ significantly in enzymatic activities and low molecular weight subunit compositions, indicating diverse capability as well as bias in degrading hemicelluloses.
